The former Warrington Wolves academy, Whitehaven, Albi, York, Oldham and Rochdale centre or wing moved in to coaching at Warrington Wizards in 2010, and progressed to head coach in 2012, retaining the position when the club merged with Woolston Rovers.
They currently play in National Conference League Division 3, finishing fifth last season.
